| Abstract | For the two of the most intersting distant galaxy cluster featuring spectacularlensing effects, Cl0024+17 and Cl2244-02 there is still an unsolved mass dis-crepancy between X-ray and lensing mass determinations. While the previous ROSATHRI and ASCA observations dont provide the means for an analysis of the tempe-rature structure of the clusters and the surface brightness at larger radii, theproposed XMM observations are ideally suited to probably resolve this discre-pancy. We will also be able to probe the core region of the clusters in detailfor a more refined comparison to the lensing models. CL0024+17 has the richeststrong lensing features and weak lensing shear has been detected out to thelargest radius in any cluster. Cl2244-02 displays the largest arc curvature. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
